My brother has Unreal and saw him play it. Going back a few years now.
Have played a cover disk demo of Unreal 2, which was pretty cool, albiet a tad slow on my system at the time.
And like I typed above, I've only played the Unreal Tournament editions - which are completely different to the normal editions - perhaps not in the graphics engine department.
I am abit hesitant on buying new games, as often the genre is the same with offering nothing new to the player; but what lies beneath in the programming department is a marvel. Gameplay should be the main reason to buy something, and not aload of technical nonsense; not unless that is, it works to improve asspects.
@O Mighty Hot one: Have you played Unreal 3? What do you recon on it?
Cheers,
Clyde.
